Application filed March 25, 1912. Serial No. 685,957.

To all whom t may concern Be it known that I, PALMER O. PoULsoN,

Y a citizen of the United States, residing at Hagerman, in the county of Chaves and State of New Mexico, have invented certain new and useful Improvements in Insoles, of which t-he following is a specilicat-ion, reference being had therein to the accompanying drawing. f

This invention relates to foot wear and -has special reference to an inflatable-insole adapted to be placed in an ordinary shoe to -cushion the foot of the wearer.

The principal obj ect of the invention isto provide a simple and etlicient device which will cushion the foot of the wearer and prevent callosities on the foot sole.

lVith the above and other objects in view this invention consists in general of certain novel constructions, hereinafter fully described and claimed.

In the accompanying drawing; like charactors of reference indicate like parts in -the several views, and: Figure 1 is a vertical ing an upper bag half as indicated at 12.

Each of these halves is provided at its front or toe end with an extension 13, which, when they have their edges cemented together,

form a tube for the inflation of the sole.

The leather strip and the inflatable bag are made to4 conform to the shape of the inside of the shoe as can readily be seen by reference to F ig. 2. Furthermore, it should be .noted that the tube extension 13 is of substantially the same thickness as the material of the bag. body so that no bulge is made at thetoe Where the tube is positioned.

Another point to be observed is that these insoles can be readily removed as they form no permanent part of the shoe.

In use the insole is inflated by blowing into the tube 13 around which a piece of twine is then bent to prevent the egress of air. The insole is then slipped into the shoe with the tube 13 bent backward. the leather side being preferably downward. The rubber, being soft and flexible, the tube will collapse and lie flatl beneath or between the wearerfs toes so that no chatlng from this source is had.

In walking' with this insole when the foot lirst strikes the ground the heel which carries the weight at this time will force the air forward toward the toe. giving a cushioning effect while when the foot leaves the ground the air is forced backward toward theheel, thus allowing gradual striking of the ball of the foot on the ground. ln-both cases contact of the foot with the solid shoe is gradualand avoids all shock.

B v reason of the detaehability of these soles av pair may be used with several different pairs of shoes'. thus avoiding the necessitv of purchasing speciallyv made shoes in order to obtain the effect of an air cushion.

There has thus been provided a simple and etlicient device of the kind described land for the purposes specilied.
